app name.apk
and right click on that file and open with HD-apk handler.exe
which is located in C:Program Files (x86)BlueStacks
.Apps
folder, which is created by default in the Libraries
folder at the time of BlueStacks installation. Then I just double clicked on the APK file to install it to the App Player. Now I can see the application icon on the home screen of the App Player and I am able to run it from there.
